Alright. I mainly used this computer for my work. Invoices. It is running windows XP and it is very slow. So, my question is, here are the specs. Should I just buy more ram in order to boost the speed or am I better off upgrading.. I don't mind gaming(medium settings) but I am not sure if a pc for gaming and work would go together well.. Operation System: Windows XP Professional Service Pack 3 Processor: Intel Pentium 4 3.00 GHz Motherboard: Asus P4P800-E Memory: 1gb DDR Ram. Video Card: Nvidia Geforce FX 5700LE This is not a prebuilt pc. The previous owner built it. I am not sure about the PSU. Might have to open it up to see. The tower is pretty big. What do you guys think?
